Dirt Resistant Chem Sealant For Car is one of our most popular products.Against moisture, dirt and other atmospheric..........

Description:

ZR300 Dirt Resistant Chem Sealant For Car is a room temperature/heating curing epoxy resin glue. ZR300 is used for design, protection of the potting need high strength or confidential electronic products.

ZR300 Bonding type organic silicon encapsulating glue used new technology without heating can well curing. When using press formulary scale thoroughly mix of A and B two components, products will form of elastic cushion material in a period of curing time.

After curing glue has the following characteristics:

Against moisture, dirt and other atmospheric composition

High strength

Easy to repair

Good adhesion performance

Has confidential role

Solvents, no cure by-products

Have stable mechanical and electrical properties between -50°C-250°C

Operation time is a quantity of cement with 100 g.

A, B two components in proportion to remove mixing ratio, mixing, vacuum suction bubble in operation period, remove the potting products to casting, such as potting product is too big, suggest points potting, then according to The Times curing(80°C/90min or 25°C/10hr)

Operation caution:

Part A and sizing material place time is too long, will produce the precipitation, the proposal is in before taking: will you please put A power mix separately, part B set period of time change color deep, this is normal phenomenon, do not affect use, after taking should pay attention to seal avoid light preservation.

Mixing should pay attention to the same direction, otherwise, it will stir with too much bubble; Borders and the bottom of the container sizing material should also stir well, can appear otherwise stir caused by uneven local not curing phenomenon.

ZR300 and contain N, S, P element of compounds and contact some heavy metal ion compounds, there will be difficult to cure or not curing phenomenon. These heavy metal ions including Sn, Pb, Hg, Bi, As, etc.
